Stand and deliver! The release of pore‐encapsulated fluorescein molecules from a core/shell mesoporous silica nanorod/superparamagnetic iron oxide nanoparticle carrier in the presence of an external magnetic field and only in response to cell‐produced antioxidants indicates promise for such systems in controlled‐release drug delivery.
